[vtkusers] Setting vtkImageData from regular float array

[Aron Helser]

HI!
Check out this example:
https://lorensen.github.io/VTKExamples/site/Cxx/ImageData/ImageIteratorDemo/

it shows how to iterate through image data and modify it's value. You can
assign values from your float array.
HTH,
Aron
